In this study, a conical-orifice injector nozzle was used. A sequence of mathematical formulae was used to guide the numerical simulations for the internal nozzle flow and spray formation. CFD (Computational Fluid Dynamics) was implemented to study the behaviors of the internal nozzle flow and the corresponding spray characteristics. Specifically, the effects of two kinds of remedies (Re-meshing Technique and Linear Interpolation Technique) on mesh deformation were compared. A more complete numerical injection model was introduced to resolve the problem of the needle opening and a detailed comparative investigation was performed pertaining to the effects of the injection process at low needle lifts on the follow-up dynamic simulation processes. In addition, an external library concept was introduced to link the process of the internal nozzle injection with the formation of spray. Comparative dynamic simulations were performed under a double-axis system. Based on the more complete numerical injection model, more details about the dynamic behaviors of the nozzle-flow simulation and the spray formation can be obtained. Furthermore, the behaviors of different potential substitute diesels have been thus investigated through the application of all numerical models that have been improved.

My name is ChaoGong. I was born on 04.03.1989 in Shandong Province of China. After obtaining my master's degree in China, I successfully got the scholarship from China Scholarship Council (CSC) and started my Pd.D study at VKM Institute of land and sea transport system of Technical University Berlin in Sep. 2013. In Sep.2017, I completed my PhD's study as planned in the field of Internal Combustion Engines and was awarded a doctorate. I work numerically and experimentally. I mainly focus on the injection and spray in diesel engine as well as the investigation on the behaviors of different fuels. During the period, I attended many international academic conferences and made some successful oral presentations. Besides, some of my academic Achievements have already been published.
